The billionaire investor posted his inaugural tweet Thursday morning, saying he thinks the microblogging site is “great” and that he likes it almost as much as Dell Inc., a company he’s currently pushing for control of.

While Twitter hasn’t verified the account yet, a spokeswoman for Icahn confirmed that the account is his.

He has only tweeted once and has gained more than 3,000 followers after his initial Twitter message.

Icahn’s move hasn’t generated as much fanfare as when Warren Buffett joined the Twitterverse last month immediately before Berkshire Hathaway 's annual meeting. Buffett has accumulated more than 490,000 followers while only publishing two tweets.

Icahn’s foray into social media isn’t his first. Five years ago he launched a blog — The Icahn Report — which he said at the time would be used as a way to spark a grassroots campaign for better treatment for shareholders. He blogged for less than a year, with his final post coming on April 16, 2009.

Icahn has also taken a sizable stake in Herbalife Ltd. and has representation on the nutritional maker’s board amid a heated battle with hedge-fund manager Bill Ackman over the legitimacy of Herbalife’s business model.
